Accepted Answer

The architecture of 2G/3G/4G networks involves multiple layers and components for communication and data transfer.

2G architecture includes Base Station Subsystem (BSS), Mobile Switching Center (MSC), and Home Location Register (HLR).
3G architecture includes Node B, Radio Network Controller (RNC), and Serving GPRS Support Node (SGSN).
4G architecture includes Evolved Node B (eNodeB), Mobility Management Entity (MME), and Serving Gateway (SGW).
Each generation introduces new technologies and enhancements to improve speed, capacity, and efficiency.
For example, 4G LTE (Long-Term Evolution) introduced IP-based architecture for faster data transfer.

4G Ip based any time anywhere voice data and multimedia at faster data rates than 3G

Accepted Answer

The infrastructure of 2G and 3G cellular networks are similar. They comprise an air interface between the user's mobile device and the base station and two core networks; one for circuit-switched voice and another for packet-switched data. In the subsequent 4G/LTE architecture, voice and data are both based on IP packets.
